Verifying email addresses is a crucial step in maintaining a healthy email list and avoiding bounces. However, verifying emails from certain domains can be challenging, especially when they use email security gateways or are set to catchall. In this blog post, we'll discuss the challenges of verifying emails from yaff.se and how BounceBan can help.
Understanding yaff.se
yaff.se is a domain that uses the Outlook.com mail protection system, as indicated by its MX records: yaff-se.mail.protection.outlook.com. This domain is set to catchall, which means that it accepts all emails sent to it, regardless of whether the email address exists or not. This setup can make it difficult to verify email addresses from this domain using traditional verification methods.
Challenges of Verifying Emails from yaff.se
Verifying emails from yaff.se can be challenging due to several reasons:
- Email Security Gateways: yaff.se may use email security gateways like Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, Sophos, etc. to filter out unwanted emails. These gateways can make it difficult to verify email addresses using simple SMTP tests.
- Catchall: As mentioned earlier, yaff.se is set to catchall, which means that it accepts all emails sent to it. This makes it challenging to verify email addresses using traditional verification methods that rely on bounce messages.
- No Bounce Messages: Even if you send a test message to an invalid email address at yaff.se, it may not always return a bounce message, making it difficult to determine whether the email address is valid or not.
Risks of Not Verifying Emails from yaff.se
If you don't verify email addresses from yaff.se, you may face the following risks:
- High Bounce Rates: If you don't verify email addresses, you may end up sending emails to invalid addresses, which can lead to high bounce rates. This can damage your sending reputation and lower your delivery rates.
- Outdated Lists: If you don't verify email addresses regularly, your lists can become outdated, leading to high bounce rates and lower engagement rates.
- Risky Emails: If you don't verify email addresses, you may end up with a list of risky emails that can harm your sending reputation and lead to account restrictions.
